摘要： A key delivery mechanism that delivers keys to an OS platform (e.g., iOS platform) devices for decrypting encrypted HTTP live streaming data. An HTTPS URL for a stateless HTTPS service is included in the manifest for an encrypted HTTP live stream obtained by an application (e.g., a browser) on an OS platform device. The URL includes an encrypted key, for example as a query parameter value. The application passes the manifest to the OS. The OS contacts the HTTPS service to obtain the key using the URL indicated in the manifest. Since the encrypted key is a parameter of the URL, the encrypted key is provided to the HTTPS service along with information identifying the content. The HTTPS service decrypts the encrypted key and returns the decrypted key to the OS over HTTPS, thus eliminating the need for a database lookup at the HTTPS service.

摘要翻译： 将键传送到操作系统平台（例如iOS平台）设备的密钥交付机制，用于解密加密的HTTP实时流数据。 用于无状态HTTPS服务的HTTPS URL包含在由OS平台设备上的应用程序（例如浏览器）获取的加密的HTTP实况流中。 URL包括加密密钥，例如作为查询参数值。 应用程序将清单传递给操作系统。 操作系统联系HTTPS服务以使用清单中指示的URL来获取密钥。 由于加密密钥是URL的参数，因此加密密钥与标识内容的信息一起提供给HTTPS服务。 HTTPS服务解密加密密钥，并通过HTTPS将解密的密钥返回给OS，从而无需在HTTPS服务中进行数据库查找。
